Moneydance on iPad no longer syncs!

As of a couple fo weeks ago I noticed my MD on ipad is n longer syncing with my Mac. recent transactions are not appearing in the iPad.
Today I entered one transaction on the iPad and when I launched MD on my Mac is failed to load.
MD on the Mac.
When I go to File-> Syncing on the Mac MD it says Sync method is Dropbox Folder and has the proper passphrase.
Currently running MD 2017.5 on the Mac I do not know how to get the current version on the iPad but it has a date of Oct 16, 2017 and says Last Sync ofis Dec 7 at 11:45 am (now)
Sync method says Dropbox has has an option to Disconnect next to it which implies it is connected.
Any ideas how to debug this?

I just changed my Sync method on the Mac to Dropbox Connection and entered the authorization code.
The transaction I entered this morning on my Ipad now showed up on my Mac an recent transactions are showing up in the ipad.
So this can be closed.
